[v3,2/2] ethdev: fix VLAN offloads set if no relative capabilities
Checks
Commit Message
Currently, there is a potential problem that calling the API function
rte_eth_dev_set_vlan_offload to start VLAN hardware offloads which the
driver does not support. If the PMD driver does not support certain VLAN
hardware offloads and does not check for it, the hardware setting will
not change, but the VLAN offloads in dev->data->dev_conf.rxmode.offloads
will be turned on.
It is supposed to check the hardware capabilities to decide whether the
relative callback needs to be called just like the behavior in the API
function named rte_eth_dev_configure. And it is also needed to cleanup
duplicated checks which are done in some PMDs. Also, note that it is
behaviour change for some PMDs which simply ignore (with error/warning log
message) unsupported VLAN offloads, but now it will fail.

v2 -> v3: Add __rte_unused to avoid unused parameter 'dev' and 'mask'
warning.
v1 -> v2: cleanup duplicated checks which are done in some PMDs.

The changes looks good but the label "next_mask" and its usage above
should also be deleted/replaced.

OK, I will delete "next_mask" and modify the function that when the offload
is not supported the function fail as below,
what do you think of it? Looking forward to your comment.
static int
dpaa2_vlan_offload_set(struct rte_eth_dev *dev, int mask)
{
struct dpaa2_dev_priv *priv = dev->data->dev_private;
struct fsl_mc_io *dpni = dev->process_private;
int ret = 0;
PMD_INIT_FUNC_TRACE();
if (mask & ETH_VLAN_FILTER_MASK) {
/* VLAN Filter not avaialble */
if (!priv->max_vlan_filters) {
DPAA2_PMD_INFO("VLAN filter not available");
return -ENOTSUP;
}
if (dev->data->dev_conf.rxmode.offloads &
DEV_RX_OFFLOAD_VLAN_FILTER)
ret = dpni_enable_vlan_filter(dpni, CMD_PRI_LOW,
priv->token, true);
else
ret = dpni_enable_vlan_filter(dpni, CMD_PRI_LOW,
priv->token, false);
if (ret < 0)
DPAA2_PMD_INFO("Unable to set vlan filter = %d", ret);
}
return ret;
}
